Intrusion is a custom Nazi Zombies map. Intrusion takes place in the same location as "Arrival", but new areas are open for gameplay.


While fighting at the NATO space base above Mars, John "Soap" MacTavish reaches the master control room. Soap activates the master controls, and a new door opens. Soap, John Price, Simon "Ghost" Riley, and Gary "Roach" Sanderson entered through the open door. When they reached the other side, the door closed. Zombies began breaking in through windows. The four S.A.S. agents pulled out their Colt M1911 .45s and started to fight more zombies. While fighting zombies, the four began notice something disturbing: zombiefied aliens.


  • American scientist zombies - The American scientist zombies in this map wear the stereotypical scientist white robe, which is bloody and wrinkled. These zombies eyes glow white.
  • American Astronaut zombies - The American astrononaut zombies are the equivalent to the Russian Cosmonaut zombies in the three previous maps. The attire of the Astronaut zombies is a white suit and a broken helment.
  • British soldier zombies - The British soldier zombies in this map wear the space-camo combat outfit. These zombies' eyes glow white, and their faces are pale and wrinkled. These zombies are quite bloody. Often, they will stumble (but not roll).
  • Aliens - The Aliens in this map do not wear clothing. They are green, with some bullet holes in them. These zombiefied Aliens are the first type of boss that appear in the Spacefront storyline. They appear every 4-5 rounds.

  • Pack-a-Punch Machine - The Pack-a-Punch Machine is exactly the same as the one in any canonical Zombie map.
  • Electro-Shock Defenses - The other utility in this map are Electro-Shock Defenses. There are a total of two Electro-Shock Defenses, which are scattered around the map. Each cost 1000 points to activate. When zombies touch the electricity bolt that is emitted from it they are immediately "fried", and die instantly. The electricity lasts thirty seconds.
